Problems solved by technology

Due to the thicker glass prism 3 of this kind of airport taxiway sideline light, more light is absorbed in the glass prism 3, and the light loss is serious, and because the middle part 4 of the glass prism 3 is hollow, it is necessary to install a cover on the prism The protective device needs to be sealed at the same time, which makes the mechanism of the lamp complicated. Due to the cover and sealing, the height of the lamp is more than 10mm above the ground height, so that there will be a certain danger when the landing or taxiing aircraft collide

Example Embodiment

[0029] Such as figure 2 As shown, in an embodiment of the airport taxiway sideline light of the present invention, it includes an LED light source 10 and a lens 20 arranged above the LED light source 10, wherein the LED light source 10 is a blue LED light source and the lens 20 is a solid lens. The light emitted by the LED light source is refracted by the lens 10 and then emitted to meet the light distribution requirements required by the airport taxiway sideline light.

[0030] See figure 2 , image 3 with Figure 4 In this embodiment, the lens 20 is a glass lens, which is made of borosilicate glass with a refractive index of 1.45 to 1.49. The lens 20 of the airport taxiway sideline lamp of the present invention includes a base 21 and upwards from the base 21 An extended tapered portion 22, the base 21 has a concave tapered surface 23 on the side facing the LED light source, and the tapered surface 23 is provided with multiple concentric toothed rings coaxial with the tapered s...

Abstract

The invention relates to an airport taxiway sideline lamp, comprising an LED light source and a lens arranged above the LED light source, wherein the LED light source is a blue LED light source, and the lens is a solid lens; the lens comprises a base platform and a conical part upwards extending out of the base platform, one side of the base platform, which is just opposite to the LED light source, is provided with a concave conical surface which is provided with multiple circles of concentric insection rings coaxial with the conical surface. Because no reflector is arranged in the airport taxiway sideline lamp, the light energy loss caused by the absorption of the reflector is reduced, and the structure of the lamp is simplified ; in addition, because the blue LED light source is directly adopted, and no additional light filter is arranged, the structure of the lamp is simplified; and moreover the LED light source has the advantages of high light-emitting efficiency, long service life and the like.

Description

technical field [0001] The invention relates to identification lights used for taxiways and guideways of airports, and more specifically relates to an airport taxiway sideline light. Background technique [0002] The airport lighting system is a visual aid to navigation. Its purpose is to better guide the aircraft to approach and land safely, especially at night and under low cloud and low visibility conditions. The airport lighting system plays an irreplaceable role. [0003] Airport taxiway sideline lights are an indispensable part of the airport lighting system. They are installed on the edges of both sides of the taxiway or not more than 3 meters away from the edge. The color of the airport taxiway sideline lights is blue, regardless of the straight part of the taxiway or the curve The light distance should be less than 60 meters, so that it can clearly display the position of the curve. When an aircraft taxis off a runway, blue airport taxiway edge lights guide pilots ...
